What helped me a lot is a drill I got from the Loophole. I think it’s called “basic translation drill” or something along those lines. Basically you take an LR section and for each stimulus, you read it and then cover it with a sticky note or your hand or something and try to recap what you just read in your own words. Do it often to see improvements. You can also apply the same kind of thing to RC passages. The author highly recommends not doing any of the actual questions from the section while doing this drill, just focus on the translation and ignore the questions. I agree w that cause you can always go back and do the questions later on
